Electrons move very slowly in copper, about 1 cm/sec. The question is the signal speed in copper, which is about half the speed of light. I got this from a couple searches in DuckDuckGo. Light in fiber is probably closer to the vacuum speed of light.

Would be slower in some other medium (like that length of fiber). And while electrons can approach the speed of light in a vacuum, they move slower in that copper wire. For example, the reason a prism bends light is that the speed of light in glass is lower than in air.
